Abstract

The purpose of the present disclosure is to enable emergency vehicles to use a high-quality NW at low cost in a movement route selection system that selects a movement route of a mobility object.　The present disclosure is a movement route selection device, which searches for route candidates from the starting point to the destination of a mobility object, and selects at least one from the route candidates on the basis of communication network information on the mobile object when the mobile object moves through the route candidates, selects a route that satisfies the communication information on the emergency vehicle from among the route candidates, when the mobility object is an emergency vehicle, and transmits a notification of traveling information or communication information to other mobility objects located on the selected route.

Description

Device, system, method and program for selecting movement route

The present disclosure relates to a travel route selection system that selects a travel route for a mobility object.

In recent years, smart mobility, such as automatic driving systems, has been actively studied (for example, see Non-Patent Document 1). When smart mobility becomes a reality, mobile objects such as vehicles will require a constant communication environment while driving in order to control automatic driving, upload various sensor information acquired by the mobile objects, and provide various services and applications to the mobile objects. be done. Furthermore, depending on the content of these communications, high communication quality is required.

When selecting a route to a destination for a mobility object, it is required to select an optimal route that takes into account various traffic information, including traffic volume. In response to this request, by acquiring information on the communication network (hereinafter referred to as "NW") along the driving route and making a judgment together with traffic information, it is possible to ensure sufficient quality of communication. It becomes possible to select the optimal route from among the driving routes provided with the NW.

On the other hand, emergency vehicles such as ambulances may perform telemedicine in addition to autonomous driving. In this case, it is desirable for the emergency vehicle to move using the shortest route while securing a high-quality NW with high priority and communication quality. However, other mobility objects may be present in the travel path of the emergency vehicle.

If only the optimal route can be set according to available NW resources, the emergency vehicle cannot select the shortest route. Furthermore, when an emergency vehicle attempts to forcibly secure communication NW resources on the shortest route, the quality of the communication NW required by other mobility objects or users other than mobility objects cannot be guaranteed.

In response, it is also possible to build a network across the country exclusively for emergency vehicles. However, although the NW dedicated to emergency vehicles is used infrequently, the amount of communication NW resources to be secured is enormous, so it is assumed that the communication NW resources are shared and allocated from among them.

The present disclosure aims to enable emergency vehicles to use a high-quality NW in a travel route selection system that selects a travel route for a mobile object.

The travel route selection system of the present disclosure includes:
A moving route selection device of the present disclosure,
a mobility object that moves along a route selected by the movement route selection device;
Equipped with.

The moving route selection device and moving route selection method of the present disclosure include:
Search route candidates from the starting point to the destination of the mobility object,
selecting at least one of the route candidates based on communication network information of the mobility object when moving the route candidate;
A moving route selection device and a moving route selection method, comprising:
If the mobility object is an emergency vehicle,
selecting a route that satisfies communication information of the emergency vehicle from among the route candidates;
Traveling information or communication information is notified to other mobility objects located on the selected route.

Here, the change in the traveling information includes changing the travel route of the other mobility object, limiting the speed of the other mobility object, or stopping the other mobility object.
Furthermore, the change in the communication information includes limiting communication network resources or stopping communication functions of the other mobility object. The notification of the communication information may also be performed to a communication device other than the mobility object located on the selected route.

As a result, the present disclosure allows emergency vehicles to use a high-quality, low-cost NW with the shortest route, and allows other mobility object users of the NW to reduce its impact.

Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the present disclosure is not limited to the embodiments shown below. These implementation examples are merely illustrative, and the present disclosure can be implemented with various changes and improvements based on the knowledge of those skilled in the art. Note that components with the same reference numerals in this specification and the drawings indicate the same components.

(First embodiment)
FIG. 1 shows a schematic configuration of the system of this embodiment. The present disclosure is a system for selecting a movement route for a mobility object 10. Mobility object 10 is any means capable of moving from a point of origin to a destination. The mobility object 10 may be a flying object 91 that can move in the air, or a vehicle 92 that can move on the ground. The mobility object 10 may be one that transports people or may be unmanned and movable. Hereinafter, an example will be shown in which the mobility object 10 is means for traveling on the ground, such as a vehicle 92, and the starting point is the current location.

The system of the present disclosure includes a travel route selection device 20 that selects a travel route from the current location to the destination. When the movement route selection device 20 receives a request from the mobility object 10, the movement route selection device 20 selects one of the route candidates (hereinafter sometimes referred to as route candidates) that the mobility object 10 can move from the current location to the destination based on the request conditions. A travel route is selected from the route and transmitted to the mobility object 10. When the mobility object 10 receives the travel route from the travel route selection device 20, it moves along the received travel route. The travel route selection device 20 of the present disclosure can also be realized by a computer and a program, and the program can be recorded on a recording medium or provided through a network.

FIG. 2 shows an example of the process executed by the travel route selection device 20. Normally, when selecting a travel route for the mobility object 10, the route selection device 20 acquires road NW information for moving from the current location to reach the destination (S21), searches for multiple routes, and selects route candidates. The route is derived (S221), and a travel route is selected from route candidates (S225). Thereby, the travel route selection device 20 selects a travel route (S22).

When selecting a travel route, the travel route selection device 20 of the present disclosure acquires communication NW information of route candidates (S222), acquires traffic information of each searched route (S223), and acquires communication NW information and traffic The cost of each route candidate is determined based on the information (S224), and the optimal travel route is selected using the cost (S225). Here, the cost is a cost related to the communication NW of the mobility object 10, and is arbitrarily determined depending on the mobility object 10 and the application being executed on the mobility object 10. Further, step S225 is periodically updated in accordance with changes in traffic information and communication NW information (S226).

In this embodiment, since the cost is determined based on the communication NW information, it is possible to select an optimal travel route that takes communication of the mobility object 10 into consideration from route candidates. Therefore, the movement route selection device 20 of the present embodiment can appropriately execute the applications executed by the mobility object 10 and the applications executed within the mobility object 10, and can control automatic driving of the mobility object 10 and the services and services provided. It becomes possible to maintain applications, etc.

Note that in this embodiment, an example has been shown in which the movement route selection device 20 selects one travel route and the mobility object 10 moves along the one travel route selected by the movement route selection device 20. but not limited to. For example, the travel route selection device 20 may select two or more travel routes, and the mobility object 10 may further select one travel route from the two or more travel routes.

FIG. 3 shows an overview of the present disclosure. The travel route selection device 20 described above is capable of selecting an optimal route and periodically re-searching for an optimal travel route. The movement route selection system of the present disclosure further includes an emergency vehicle adjustment procedure S23 for ensuring the quality of the communication NW required by the emergency vehicle 10M of the mobility objects 10.

In the emergency vehicle adjustment procedure S23,
(i) Notification of travel information or communication information to other mobility objects 10N,
(ii) notification of communication NW information to 60 other than mobility objects;
is made possible at irregular intervals (interrupts).
Note that in this embodiment, the other mobility object 10N is the vehicle 92, but the other mobility object 10N is not limited to the vehicle 92, but may be any means that can become the mobility object 10, such as the flying object 91.

Specifically, for the other mobility object 10N, the communication NW information and position information of the other mobility object 10N are acquired (S232), and the notification content for the other mobility object 10N is determined (S233). The notification contents include a notification of driving information and a notification of communication information. The notification of travel information includes, for example, any request regarding the travel conditions, such as changing the travel route of the other mobility object 10N, limiting the speed of the other mobility object 10N, or stopping the other mobility object 10N. The communication information notification includes, for example, any request for communication conditions such as limiting the communication network resources or stopping the communication function of the other mobility object 10N. Thereby, the movement route selection device 20 restricts the use of the NW of other mobility objects 10N.

In the notification to the non-mobility object 60, position information of the non-mobility object 10 is acquired (S234). Thereby, the movement route selection device 20 notifies communication NW information such as restriction of communication network resources or suspension of communication functions to 60 other than mobile objects.

The movement route selection device 20 of the present disclosure incorporates a functional unit that executes the adjustment vehicle adjustment procedure S23 for vehicles with high priority and required NW quality such as emergency vehicles, thereby providing the shortest route with high quality and low cost. It is possible to construct a mechanism that allows the emergency vehicle 10M to use the NW, and also allows other mobility objects 10N and 60 users of the NW other than mobility objects to reduce its influence. For example, it is possible to realize speed restrictions such as slow driving due to functional limitations of the communication NW of other mobility objects 10 through which the emergency vehicle 10M passes.

The location information management system 84 is a system that manages location information of 60 other than mobile objects and identifiers for identifying users based on real-time information such as GPS (Global Positioning System), and can provide this information to the outside.

The travel route selection system 85 selects an optimal travel/flight route that can maintain communication quality based on the current location/destination information of the mobility object 10, information on roads, traffic, etc., as well as communication NW information, and manages the information. This is a system for notifying external systems such as systems 81 to 84, the mobility object 10, and non-mobility objects 60.

The driving route selection system 85 is communicatively connected to the mobility object 10, the non-mobility object 60, the road NW information management system 81, the communication NW information management system 82, and the traffic information management system 83. The mobility object 10 and the non-mobility object 60 are communicably connected to the travel route selection system 85 using some kind of communication NW (wireless/satellite/beacon, etc.). Further, the road NW information management system 81, the communication NW information management system 82, and the traffic information management system 83 may be independent, or may be interconnected or integrated.

FIG. 6 shows an example of external information collection processing that is periodically performed in each of the information management systems 81 to 84 and the travel route selection system 85.
The driving route selection system 85 periodically requests information from each of the information management systems 81 to 84 (S111), collects the latest information from external systems such as the information management systems 81 to 84, and links the collected information. and is managed by the external information management unit 23 (S117).

Each of the information management systems 81 to 84 is updated and managed by the "information management department" to the latest information, whether regularly or irregularly. The information management systems 81 to 84 process the information they hold based on a request from the driving route selection system 85 and notify it (S112 to S116).

FIG. 8 shows an example of a driving route selection process that is irregularly performed in the driving route selection system 85.
(Mobility object 10)
The driving information management unit 12 requests a driving route to the destination using an arbitrary trigger (S131). When requesting a driving route, request conditions are set based on the policy information registered in the policy information management section 14 at that time and other information managed by the information management section 15 (S132, S133). , requests the driving route selection system 85 for a driving route to the destination based on the current position information (S134).
When the driving information management unit 12 receives the optimal driving route from the driving route selection system 85, it performs driving control based on the route information (S138).

(Driving route selection system 85)
When the mobility object 10 requests a travel route, the mobility object information management unit 24 checks the requirements of the mobility object 10 and requests the travel route calculation unit 22 to calculate the travel route (S135).
The travel route calculation unit 22 extracts necessary information from the external information management unit 23 based on the requirements from the mobility object information management unit 24, and calculates an optimal travel route (S136). For example, within the 5G area of a specific carrier, time priority, etc. After calculating the optimal travel route, it is notified to the mobility object 10 via the optimal route notification unit 25 (S137).

In step S136, if there is a change in traffic information or communication NW information due to the regular update of the external information management unit 23, the optimal travel route is recalculated based on the position information of the mobility object 10 at that time. At this time, if the optimal travel route changes, the mobile object 10 is notified again via the optimal route notification unit 25.

FIG. 9 shows an example of a travel route selection process when the mobility object 10 is an emergency vehicle 10M. The driving route selection system 85 selects a driving route based on the communication NW information (S135, S146) based on a request from the emergency vehicle 10M of the mobility objects 10 (S134), and selects a driving route based on the communication NW information (S135, S146). After the adjustment is made by the adjustment unit 26 (S153), the emergency vehicle 10M, other mobility objects 10N, and non-mobility objects 60 are notified (S147, S154).

When the emergency vehicle 10M requests a travel route shown in steps S131 to S134 in FIG. requirements are set based on the quality) and other information managed by the information management section 15, and a request is made to the travel route selection system 85 for the shortest travel route to the destination based on the current location information. This request may include a communication NW function restriction request for any communication device on the travel route.
When the emergency vehicle 10M receives the shortest travel route from the travel route selection system 85, it performs travel control based on the route information (S148M).

For mobility objects 10N other than the emergency vehicle 10M, measures are taken in response to requests from the emergency vehicle coordination unit 26. Specifically, the driving information management unit 12 changes the route to a detour route based on the notification from the driving route selection system 85 (S148N). Further, the driving information management unit 12 instructs to temporarily change the policy information (S155), and the policy information management unit 14 temporarily changes the policy information and performs speed limit/stop driving control (S156). .

In the non-mobility object 10, the notification information processing unit 62 displays communication restriction information (route and degree of NW restriction) in a form visible to users other than the mobility object 10, based on the notification from the driving route selection system 85 (S157 ).

When the travel route calculation unit 22 of the travel route selection system 85 receives the request from the emergency vehicle 10M, it executes the following step S146 in place of step S136 in FIG. In step S146, the driving route calculation unit 22 starts calculating the driving route based on the requirements from the emergency vehicle 10M (S151). Next, the shortest travel route candidate is calculated based on the road NW information and traffic information from the external information management unit 23 (S152).

In response to a request from the emergency vehicle 10M, the emergency vehicle coordination unit 26 of the driving route selection system 85 irregularly (interrupts) determines whether or not to release NW resources and requests notification in accordance with the determination result. FIG. 10 shows an example of the operation of the emergency vehicle adjustment section 26 in step S153.

When there is a travel route request from the emergency vehicle 10M with the highest required quality, the emergency vehicle adjustment unit 26 receives information about the travel route from the travel route calculation unit 22, and performs flow A or flow A. Perform flow B. Flow A and flow B may be performed singly or in parallel.

In flow A, the emergency vehicle coordination unit 26 requests the external information management unit 23 for information necessary for determining whether to release communication NW resources based on the received travel route (S161).
Based on the received information, the emergency vehicle coordination unit 26 determines whether it is necessary to release communication NW resources (S162), whether a detour is possible (S163), whether speed restrictions such as slow driving are necessary (S165), and whether communication It is sequentially determined whether the NW function needs to be stopped (temporarily stopped on the roadside) (S167).
Then, if a detour is possible (Yes in S163), the detour route is notified through the optimal route notification unit 25 (S164, S147).
In addition, in the case of NW function restriction/stop (Yes in S165, Yes in S167), a notification is sent to the mobility object 10N through the NW restriction notification unit 27 (S166, S168, S154).

In flow B, the emergency vehicle adjustment unit 26 determines whether the non-mobility object 60 uses the communication NW resource on the travel route based on the position information (S171, S172), and sends the information to the non-mobility object 60 via the NW restriction notification unit 27. Notify (S154).

(Second embodiment)
A method for calculating the cost for each route (step S224 shown in FIG. 2) will be described with reference to FIG. 11. The travel route calculation unit 22 searches for route candidates from the departure point _PA to the destination _PD based on the road NW information and traffic information. As a result, the traveling route calculation unit 22 derives three route candidates: a route R1 passing through the sections S1 and S2, a route R2 passing through the sections S3 and S7, and a route R3 passing through the sections S3 to S6.

The driving route calculation unit 22 acquires communication NW information for routes R1 to R3, which are route candidates. As a result, the driving route calculation unit 22 determines that antennas A2 and A1 can be used in section S1, antennas A6 and A7 can be used in section S2, antenna A3 can be used in section S3, and antenna A3 can be used in section S4. Acquires that antenna A9 is available, antennas A4 and A5 are available in section S5, antenna A8 is available in section S6, but no usable antenna is arranged in section S7. do.

The driving route calculation unit 22 also acquires policy information. If this policy information includes a communication policy that excludes routes that include sections without antennas (no communication) from route candidates, the driving route calculation unit 22 replaces route R2 including section S7 with Exclude from candidates. In this way, the communication NW information is determined based on the communication policy of the mobility object 10. On the other hand, routes R1 and R3 do not include an antenna-less (communication impossible) section. In this case, the driving route calculation unit 22 calculates the costs of the routes R1 and R3 based on information on antennas that can be used in each section.

Although the method for calculating the cost is arbitrary, an example is to calculate the average cost for each section and calculate the total sum. Specifically, if the external information management unit 23 stores the total cost for each antenna as shown in FIG. 22 can be calculated using the following equation.
・Cost of route R1:
(Average cost of section S1) + (average cost of section S2)
=((13+13)/2)+((15+9)/2)=13+12=25
・Cost of route R3:
(Average cost of section S3) + (Average cost of section S4) + (Average cost of section S5) + (Average cost of section S6)
=8+5+(5+5)/2+8=8+5+5+8=26
In this case, the travel route calculation unit 22 selects the low-cost route R1.

If the communication policy specifies that priority is given to communication quality, the driving route calculation unit 22 can calculate the cost of route R1 as 153 and the cost of route R3 as 98 using the same calculation formula. In this case, the travel route calculation unit 22 selects the low-cost route R3.

As explained above, the present embodiment calculates an optimal driving route candidate based on road NW information and traffic information, and uses communication NW information on the calculated driving route to determine whether it is the optimal driving route. By making this determination, it becomes possible to link communication network status understanding and route selection.
